Benefits of technology
Enables effective flattening and leveling of mother plates, ensuring geometric deviations fall within tolerances, thereby enhancing the cathode's performance in electrolytic recovery processes while maintaining the integrity of the hanger bar support.
Problems solved by technology
Because permanent cathodes normally are provided with a hanger bar for supporting the permanent cathode on the edges on an electrolytic cell so that the mother plate of the permanent cathode is sank in the electrolyte in the electrolytic cell, flattening and leveling of a mother plate by rolling is difficult to perform.

Embodiment Construction
[0015]The FIGURE shows an example of a method and an apparatus according to the invention.
[0016]First the method for preparing a mother plate 1 of a permanent cathode 2 to be used in a process for electrolytic recovery of metal such as metal electrorefining or metal electrowinning and preferred variations thereof will be described.
[0017]The mother plate 1 is an object in the form of a plate that has two opposite faces (not marked with a reference numeral) on which metal is collected in a process for electrolytic recovery of metal such as metal electrorefining or metal electrowinning.
[0018]The method comprises a step for releasably holding the permanent cathode 2.
[0019]The method comprises a step for measuring a shape of the mother plate 1 of a permanent cathode 2 with a measurement device to obtain measurement data.
[0020]The method comprises a step for calculating geometric deviation of the mother plate 1 in comparison to a predefined reference shape by using said measurement data.

Abstract
The invention relates to a method and an apparatus for preparing a mother plate of a permanent cathode to be used in a process for electrolytic recovery of metal such as metal electrorefining or metal electrowinning. The apparatus comprises a holder for releasably holding the permanent cathode, a measurer for measuring a shape of the mother plate to obtain measurement data, a calculating device functionally connected with the measurer and configured for calculating geometric deviation of the mother plate in comparison to a predefined reference shape by using the measurement data, and a presser functionally connected with the calculating device and configured for automatically locally pressing the mother plate in accordance with the calculated geometric deviation of the mother plate to plastically deform the mother plate.
Description
[0001]This is a national stage application filed under 35 USC 371 based on International Application No. PCT / FI2010 / 050563 filed Jun. 30, 2010 and claims priority under 35 USC 119 of Finnish Patent Application No. FI 20095740 filed Jun. 30, 2009.FIELD OF THE INVENTION[0002]The invention relates to a method for preparing a mother plate of a permanent cathode to be used in a process for electrolytic recovery of metal such as metal electrorefining or metal electrowinning as defined herein.[0003]The invention also relates to an apparatus for preparing a mother plate of a permanent cathode to be used in a process for electrolytic recovery of metal such as metal electrorefining or metal electrowinning as defined herein.[0004]The invention relates more precisely to a method and apparatus for automatically flattening and leveling mother plates of permanent cathodes used in electrolytic recovery of metals such as zinc, copper or lead. A mother plate of a permanent cathode can for example be ...
